Title: Piston ring
Inventor: GOTOU TAKAHARU
IPC: F16J9/14
Filed: 1983-10-21
Abstract: PURPOSE:To enhance the sealing effect of a piston ring, by forming a notch in one of the terminal ends of the piston ring which are opposed to each other with a joint gap therebetween, the notch being extended from the lower edge of the slide surface of the piston ring to a position above the substantially diagonal line of the ring cross-section, and as well by forming a projection having a shape complementing the notch, in the other end of the piston ring. CONSTITUTION:A notch 25a which is extended from the lower edge of the slide surface 24 of a piston ring 21 to a position below the diagonal line of the ring cross-section and over a predetermined length in the circumferential direction, is formed in one of a pair of terminal ends 23a, 23b of the piston ring 21 which are opposed to each other with a joint gap 22 therebetween. A projection 25b of a substantially triangular shape complementing the notch 25a, is formed in the other end 23b of the piston ring 21. With this arrangement, when the piston ring 21 is pressed against the upper surface of a ring groove 26, a second joint gap 28 is communicated with a combustion chamber side only through a slight gap between the projection 25b and the notch 25a and the first joint gap 22.

Inventor: KAI TOSHIHIRO
IPC: H04N9/78
Filed: 1990-07-23
Abstract: PURPOSE:To reduce the effect of leakage of a luminance signal and a chrominance signal to mutual channels by detecting the correlation between pictures in horizontal and vertical directions of a composite color television signal and selecting an output signal of a luminance signal chrominance signal separation filter with a different characteristic based on the result of detection and outputting the signal. CONSTITUTION:A switch circuit 23 selects a color output signal of a vertical direction chrominance signal extraction filter 16, a horizontal chrominance signal extraction filter 19 and horizontal/vertical chrominance signal extraction filter 17. The detection of the correlation of the picture and the control of the switch circuit 23 are implemented by a picture correlation discrimination circuit 18. That is, when the vertical correlation is weak and the horizontal correlation is strong in a sampled value at a noted sampling point, a 1st color signal extracted by the horizontal chrominance signal extraction filter 19, when the vertical correlation is strong and the horizontal correlation is weak in the sampled value at the noted sampling point, a 2nd color signal extracted by the vertical chrominance signal extraction filter 16, and when not in the cases above, a 3rd color signal extracted by the horizontal/vertical chrominance signal extraction filter 17 are selected as the color signal selection.

Title: Magnetic record medium
Inventor: KAWARAI MASAYOSHI
IPC: G11B5/735
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To obtain a medium suitable for short wavelength recording and to suppress increase in noise after long-term storage by forming a magnetic coating film containing a metal magnetic powder on one surface of a base body and forming a back coating layer containing a carbon black of primary particles or aggregates having a larger particle size than the major axial diameter of the metal magnetic powder on the other surface. SOLUTION: The major axial diameter of the metal magnetic powder used for the magnetic coating film is specified to <=0.8 μm considering the center recording wavelength and is preferably 0.2 μm from the viewpoint of resolution. As for carbon black, carbon black having various particle sizes is easily available and can be properly selected considering the major axial diameter of the metal magnetic powder. If the particle size of the carbon black is rather small, aggregates of several primary particles are prepared. Thereby, the obtd. medium gives high output for short wavelength recording with about <=0.8 μm center recording wavelength which is required for a small-size video tape of high picture quality, and increase in noise due to storage is prevented.

Title: Dram memory cell
Inventor: BINGUUUEI SHIEN
IPC: H01L27/108
Filed: 1990-07-25
Abstract: PURPOSE: To make a tolerance for a positioning error unnecessary by a method, wherein a DRAM cell is provided with a trench, a first electrode is formed of a diffusion region located on the surface outside the trench provided inside a substrate, and a second electrode is composed of a conductive region formed inside the trench. CONSTITUTION: A trench region (covered with a silicon dioxide layer 27) where a substrate is exposed is left on a field plate 28 and a part where a substrate 10 is covered with word lines 40 and 44. Source/drain regions are formed by implanting ions using the field plate 28 and word lines as masks, wherein the word lines 40 and 44 serve as the above word lines, whereby a gate and the field plate 28 are automatically aligned with each other. By the above automatic alignment, an additional positioning tolerance for forming the source/drain regions of a transfer transistor 11 becomes unnecessary, so that an additional masking process which causes a yield reduction can be dispensed with. A capacitor structure is indicated by trenches 18 and 20.

Title: Atm communication system in dual ring network
Inventor: TSUTSUI KOJI
IPC: H04L12/70
Filed: 1990-07-27
Abstract: PURPOSE:To allow each node on a ring transmission line to easily restart the communication by separating an ATM cell only when information from the ring transmission line receiving an ATM cell and information by 2nd identification information are coincident and information of 1st identification information is only the information relating to a node number of a separated node. CONSTITUTION:Let a ring transmission line clockwise be a 0 system ring and a ring transmission line counter clockwise be a 1 system, then each node has a function of loopback connection of a 0 system ring output to a 1 system ring input and a 1 system ring output to a 0 system ring input so as to allow both nodes 1-3,1-4 at both ends of, e.g. a fault location 2 to activate a loopback function. On the other hand, as a VPI(virtual path identifier) as an asynchronous transfer mode(ATM) cell header information, the same 1st identification information (a) is defined in two-ways between an inserted node 1-2 and a separated node 1-4 and transmission line identification information identifying the 0 system ring and the 1 system ring is defined. Thus, the fault is coped with by allowing nodes at both ends of the fault location 2 to have only to apply loopback connection to the ring.

Title: Automatic tuning device
Inventor: KOKUBU KATSUO
IPC: H03J7/18
Filed: 1982-11-12
Abstract: PURPOSE:To attain the optimum tuning by having tuning to a pseudo TV signal and then switching said TV signal to a broadcast signal. CONSTITUTION:A crystal oscillator 7 oscillates a signal of frequency of a desired channel, and this signal is supplied to a varactor tuner 5. The tuning voltage is supplied to the tuner 5 from a channel selector 8, and a tuning operation is carried out. The selector 8 compares phases between an IF signal and a reference signal generated from the oscillator 7 and then produces the optimum tuning voltage. The desired TV signal is applied to the tuner 5 in place of the output signal of the oscillator 7 when the tuner 5 has its optimum tuning state. The tuning time can be reduced since the tuning to the non-modulated signal is carried out first.

Title: X-ray radiographing device
Inventor: FUJII TADASHI
IPC: G03B42/02
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To smoothly retreat a supporting plate in a hermetically sealed space by separating both supporting structures, when the positive pressure is detected during the supply of air into the hermetically sealed space, after photographing is completed. SOLUTION: The air enters into the hermetically sealed space from a nozzle, to release the closely sticking of a film and a screen. Further, the air is supplied into the hermetically sealed space by a vacuum pump 81, to attain pressurization. The air is supplied by the use of exhaust gas from the vacuum pump 81, by switching the connection of a piping part 70 with an electromagnetic valve 82. When the fact that the hermetically sealed space becomes a positive pressure state is detected by a pressure sensor 72, during the supply of the air into the hermetically sealed space by the vacuum pump 81, the retreat of a rear side supporting plate is started. At this time, the air at a flow rate greater than the volume variation per unit hour of the hermetically sealed space, accompanying a retreating operation is supplied by the pump 81, to smoothly execute the retreating operation.  Thus, both supports are completely separated.
